Note: Please contact specific facilities for additional information. Sign up for the APG Website Electronic Mailing List to receive a notice when this list is updated. There are specific situations outlined in the APG DTC Ancillary policy when clinic providers not listed above can bill Medicaid for ancillary services and then pay ancillary services providers directly. It is never appropriate for both an ancillary services provider and a clinic to bill for an ancillary service. List additions, deletions, or questions about the ancillary policy should be sent to APG@health.state.ny.us.
